G&L L-2500 S750 - Review

Nice report! And awesome looking bass! I love my L2K. Previous owner did the K Mod and it's a nice, muscular jazz tone, but my L2K lives in series mode 99% of the time. I took the battery out too. I'm almost thinking of removing the preamp out altogether, which is just a line driver and/or line driver + treble boost anyways and totally not needed with my gear and setup. Oh but that thick mid rich tone in series mode is just fantastic.

Thanks! Yeah mine lives in parallel most of the time. My tech asked me if I wanted to go down the full passive route while he was doing the K-Mod but I thought it was better to have and not need the preamp (plus my OCD won't let me have a battery slot that isn't connected to anything..)

So, after a little over a year of owning it (& as there aren't many reviews on these) I thought I'd share my thoughts on my G&L L-2500 S750, which LowEndLobster kindly sold to me and reviewed herself.

Overall, my go to bass. Unmatched tone-wise and a real looker. However, to avoid bias, here are some pros & cons:

PROS:

- MFD pickups are out of this world, better than anything else on any of my basses, & are the main reason I always use it.
- Preamp is great too, albeit a little unconventional. I love having what are essentially passive treble and bass tone knobs. I also like the pickup selector switch rather than a knob, as it simplifies an already complicated tonal palette. The active options are also nice although I run mostly passive.
- Neck, which is chunkier, & the 19mm spacing are perfect for my hands (which are on the larger side).
- K-MOD, although done by my local guitar tech rather than G&L, adds even more to the bass. I only use it for a proper J tone (rather than single neck coil etc..) as it scoops an already very mid-y bass quite nicely.
- It kicks all the time (which I'll also pop in the cons) meaning whether you're solo or mixed, it cuts and punches, which is ace assuming that's what you want..
- General sturdiness is great, feels solid and reliable, balances well, resonates nicely, although there's a con coming with that too..

CONS:

- Gloss on the neck was so thick.. Lobster didn't mind it, I did, so I made it satin, easy fix.
- Weight is a tad heady, not crazy, 4.5kg maybe, but a good strap goes a long way.
- Action refuses to go low. To clarify, when I say low I mean like my Sandberg which ignores the laws of physics.. it'll sit just under fender specs quite happily, but try & take lower and it'll just complain constantly. I had the same thing (worse, actually) with an old L-2000.
- The low B is ok, not amazing.. it's only a 34" scale, & my main comparison is a Lakland 35" 5er, so I'm possibly judging a little harshly.
- The big one.. G&L's famous electronics problems meant a pickup died randomly.. my tech couldn't work out why & it had to be replaced. Rubbish situation however it lead to the K-MOD so, there we are.
- As above, it kicks all the time.. Which is to say even when the tone knobs are all the way down, it still feels like it's trying to punch you in the face. More a character of the instrument, however it lands in the cons too because if you want polite, just don't ask..

Overall, I love it. It's got an attitude, & I genuinely think it has days where it loves me, and days when it would garrotte me if it could, which is.. fun..? However, when the GAS takes over & I watch videos of F Basses etc, I'm always left thinking my G&L sounds more versatile, punchy, gorgeous etc & the GAS dies (a little..).

Anyway, there we are.. I'll link a video of the K-MOD..

Please if you ever decide to sell. DM me. I'm scowering the internets for one. I watched Lobsters video and asked her if she had, said no Just the L-1000. So funny to find it here.

Will do, although it won't be any time soon, just so you know! ❤️
OMG hello old friend

Googling, it looks like S750 means the string spacing is wider. What's the K-Mod? Sorry for the newbie questions.

Not sure what the K stands for…
Old question, I know, but I don't believe it was answered.
K in K-mod stands for Korean, because in the early 2000's the L2500's set for the the Korean import market had the Single Coil feature. Not sure why the Korean market got it and not the US, but it became the K-mod when US buyers found out about it and wanted their L2500's modded for the SC option.
I believe Steve Araujo had a small explanation about it in one of the more recent L2500 videos.

I also modded my L2500 for SC myself. I use it most of the time, as well as Parallel. I never use Series as I find it too Middy and Muddy.
I suppose it's a safe to say that I use Single Coil most of the time because I don't own a proper Jazz bass…
 
Citing Paul Gagon in another forum, this design is called "K-wiring" because it was a request from Kurosawa, a G&L distributor in Japan.
Another commonly found name is K-switch.

I think it's what I have from origin on my 2017 Kiloton-5, the switch middle position is for SC : Series-SC-Parallel.
My preferred mode is parallel. Series is very powerful.
I had made all my G&L L-series basses modded with the K-switch attachment: two ASAT basses, an L-2500 Custom, and an M-2500 USA.

I'm kind of surprised to hear the B string isn't as robust as I've hear others boast of. Any feedback from other 750 owners?
Your question got a little buried so thought I'd bump and give a little more context. It's solid enough, loud and present, it just lacks clarity (regardless of string gauge/type & setup) and mostly, sustain. It also buzzes if you even think about putting the action past medium/low.

It's probably as good as many, however my Lākland and my mate's Stingray are significantly better, to the extent that when I play my Lākland, I have to remind myself to treat the B like every other string, rather than playing away from it.

Would it make sense if I said I sounds like an "add on" and not part of the overall intention of the instrument..? That's the best way I can describe it. I'm probably being over critical but at this price point, I feel like it's justified.
